Going to the store tomorrow, going to buy the kit that has the plunger in it and see about flushing my ear out. If this doesn't work the next stop is the urgent care. I tried to use more hydrogen peroxide today and that just made things worse. The weird thing is if I pull the skin near my ear tight or like swish around my ear with my hand I hear it pop and like kind of open up. I even tried doing the trick of closing my nose with my hand and blowing on my ear drums and it almost feels like it wants to pop. But I realize that way is dangerous and I could pop my ear drum.
This happens to me a lot. Probably a wax buildup that's blocking the ear canal, and slight adjustments make a slight opening or vary the pressure to the point where it FEELS like something's happening, but isn't. I've just gone to a clinic to get mine cleaned out.
A few months ago I bought an ear camera/cleaner off Amazon for about 40 bucks and try to use it regularly, but it's a lot harder to navigate than I thought it'd be, and it gets pretty hot after a few minutes.
The problem hasn't recurred since, though. But it's the sort of thing that only happens once every year or two, so who knows.
I hope you can get it taken care of soon. Plugged ears are a literal and figurative headache.
